Steel Coal Strike Butterfly Knife.The spear point blade is made from stainless steel and edged on one side. The two types of fullers that run down the center, gives this blade a wicked impression. The handles are double walled with a steel frame. You can see the shining from coming through the circular cutouts so that they look like tiny mirrors along both sides of the handle. A safety latch is provided for locking your blade opened or closed but the best part has to be the stonewash finish that you can see on both the blade and handle.
